**Answer:**

0.1 mm

**Explanation:**

60 sheets = 6 mm

We want 1 sheet so we divide both sides by 60 :

1 sheet = 6/60 mm

1 sheet = 1/10 mm

1 sheet is 0.1 mm

**Answer : The correct option is, X : radius and Y : tangential speed**

**Explanation :**

**Centripetal force : ** It is defined as a force which acts on the object to keep the object moving along a circular path.

**Formula for centripetal force :**

where,

= centripetal force

m = mass

r = radius

V = tangential speed

The quantity belong in cell **X **is **radius** and in the cell **Y **is **tangential speed**

**Hence, the correct option is, X : radius and Y : tangential speed**

**Answer: well the time it takes to fall 100m is the same time it takes to travel 65m horizontally. **

**The time to fall vertically, t is sqrt(2d/g). [this comes from d = 1/2at^2] **

**so t = sqrt(2*100/9.8) = 4.52s. **

**The vertical speed at that time is g*t = 9.8*4.52 = 44.3m/s **

**The horizontal speed is the horizontal distance over the same 4.52s, = 65/4.52 = 14.4m/s. **

**so the final velocity is = sqrt(44.3^2 + 14.4^2) = 46.6m/s **

**Explanation: yes **
